The Elements of Weather

Understanding Basic Concepts
- explain the difference between weather and climate and the factors that influence both of these systems
- identify patterns in air movement
- identify the effects of air pressure


What is Weather?

http://oncampus.richmond.edu/academics/education/projects/webunits/weather/how.html

1. Define weather.Weather occurs in the part of the earth's atmosphere called the troposphere.
2. What four factors affect weather

  • the air
  • the sun
  • water
  • the earth's movement

Weather vs Climate

3. What is the difference between climate and weather?Climate is about long-term records, trends and averages;
Weather is the day to day experience.

Measuring the Weather

Developing Skills of Inquiry, Design and Communication
- design, construct, and test a variety of weather instruments
- use appropriate vocabulary, including correct science and technology terminology, in describing their investigations and observations


The following web site describes some of the instruments meteorologists use to collect data about the weather.

Clouds

Understanding Basic Concepts
- explain the formation of clouds and the effects of different cloud formations on weather and climate


Use this web site to answer the following questions.
http://oncampus.richmond.edu/academics/education/projects/webunits/weather/clouds.html
1. What are clouds?Clouds are a visible mist of billions of water and ice particles floating in the sky.
2. Explain how clouds form.They are form by ice particles floating in the sky.
3. What are the 3 "families" of clouds and what do their Latin names mean?Cirrus,cumulus,and stoatus.
4. Follow the links to learn about each type of cloud and then complete the table on the next page.
To help you identify clouds, download, print and construct the following "Cloud Key".

Forecasting

Understanding Basic Concepts
-recognize large-scale and local weather systems
- predict local weather patterns using data from their own observations of weather and from weather reports
- identify patterns in air movement
